2020-07-06RDMA/core: Clean ib_alloc_xrcd() and reuse it to allocate XRC domainMaor Gottlieb
ib_alloc_xrcd() already does the required initialization, so move the uverbs to call it and save code duplication, while cleaning the function argument lists of that function.

2020-07-06Merge branch 'mlx5_ipoib_qpn' into rdma.git for-nextJason Gunthorpe
Michael Guralnik says: ==================== This series handles IPoIB child interface creation with setting interface's HW address. In current implementation, lladdr requested by user is ignored and overwritten. Child interface gets the same GID as the parent interface and a QP number which is assigned by the underlying drivers. In this series we fix this behavior so that user's requested address is assigned to the newly created interface. As specific QP number request is not supported for all vendors, QP number requested by user will still be overwritten when this is not supported. Behavior of creation of child interfaces through the sysfs mechanism or without specifying a requested address, stays the same. ==================== Based on the mlx5-next branch at git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux due to dependencies. * branch 'mlx5_ipoib_qpn': RDMA/ipoib: Handle user-supplied address when creating child net/mlx5: Enable QP number request when creating IPoIB underlay QP Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>

2020-07-03net/mlx5: Enable QP number request when creating IPoIB underlay QPMichael Guralnik
If in the process of creating the underlay QP for an IPoIB interface the user has set the address and specifically the 1st-3rd bytes representing the QP number, use the requested QP number when creating the underlay QP. For a user to be able to request a QP number on QP creation, the MKEY_BY_NAME NVCONFIG should be set. As mkey_by_name and qp_by_name are coupled in FW. This requires driver to query the mkey_by_name max cap during initialization and set the current cap if it was enabled in FW.

2020-07-02RDMA/core: Fix bogus WARN_ON during ib_unregister_device_queued()Jason Gunthorpe
ib_unregister_device_queued() can only be used by drivers using the new dealloc_device callback flow, and it has a safety WARN_ON to ensure drivers are using it properly. However, if unregister and register are raced there is a special destruction path that maintains the uniform error handling semantic of 'caller does ib_dealloc_device() on failure'. This requires disabling the dealloc_device callback which triggers the WARN_ON. Instead of using NULL to disable the callback use a special function pointer so the WARN_ON does not trigger.

2020-07-02RDMA/ipoib: Fix ABBA deadlock with ipoib_reap_ah()Jason Gunthorpe
ipoib_mcast_carrier_on_task() insanely open codes a rtnl_lock() such that the only time flush_workqueue() can be called is if it also clears IPOIB_FLAG_OPER_UP. Thus the flush inside ipoib_flush_ah() will deadlock if it gets unlucky enough, and lockdep doesn't help us to find it early: CPU0 CPU1 CPU2 __ipoib_ib_dev_flush() down_read(vlan_rwsem) ipoib_vlan_add() rtnl_trylock() down_write(vlan_rwsem) ipoib_mcast_carrier_on_task() while (!rtnl_trylock()) msleep(20); ipoib_flush_ah() flush_workqueue(priv->wq) Clean up the ah_reaper related functions and lifecycle to make sense: - Start/Stop of the reaper should only be done in open/stop NDOs, not in any other places - cancel and flush of the reaper should only happen in the stop NDO. cancel is only functional when combined with IPOIB_STOP_REAPER. - Non-stop places were flushing the AH's just need to flush out dead AH's synchronously and ignore the background task completely. It is fully locked and harmless to leave running. Which ultimately fixes the ABBA deadlock by removing the unnecessary flush_workqueue() from the problematic place under the vlan_rwsem.

2020-06-22samples: watch_queue: build sample program for target architectureMasahiro Yamada
This userspace program includes UAPI headers exported to usr/include/. 'make headers' always works for the target architecture (i.e. the same architecture as the kernel), so the sample program should be built for the target as well. Kbuild now supports 'userprogs' for that. I also guarded the CONFIG option by 'depends on CC_CAN_LINK' because $(CC) may not provide libc. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-06-22Revert "Makefile: install modules.builtin even if CONFIG_MODULES=n"Masahiro Yamada
This reverts commit e0b250b57dcf403529081e5898a9de717f96b76b, which broke build systems that need to install files to a certain path, but do not set INSTALL_MOD_PATH when invoking 'make install'. $ make INSTALL_PATH=/tmp/destdir install mkdir: cannot create directory ‘/lib/modules/5.8.0-rc1+/’: Permission denied Makefile:1342: recipe for target '_builtin_inst_' failed make: *** [_builtin_inst_] Error 1 While modules.builtin is useful also for CONFIG_MODULES=n, this change in the behavior is quite unexpected. Maybe "make modules_install" can install modules.builtin irrespective of CONFIG_MODULES as Jonas originally suggested. Anyway, that commit should be reverted ASAP.

Vaibhav explains in the merge commit below why missing v5.8 would be painful and I agreed to try a -rc2 pull because only cosmetics kept this out of -rc1 and his initial versions were posted in more than enough time for v5.8 consideration: 'These patches are tied to specific features that were committed to customers in upcoming distros releases (RHEL and SLES) whose time-lines are tied to 5.8 kernel release. Being able to track the health of an nvdimm is critical for our customers that are running workloads leveraging papr-scm nvdimms. Missing the 5.8 kernel would mean missing the distro timelines and shifting forward the availability of this feature in distro kernels by at least 6 months' Summary: - Fix the visibility of the region 'align' attribute. The new unit tests for region alignment handling caught a corner case where the alignment cannot be specified if the region is converted from static to dynamic provisioning at runtime. - Add support for device health retrieval for the persistent memory supported by the papr_scm driver.
